[0034] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0035] The present invention provides an audio system comprising: a signal transceiver module, an audio codec module, an audio output circuit selection module, a first audio output circuit, a second audio output circuit, and an electroacoustic conversion unit; wherein, the signal transceiver module is used to receive a target audio signal, the target audio signal being a first audio signal or a second audio signal with a higher priority than the first audio signal; the audio codec module is used to convert the digital form of the target audio signal into an analog form to obtain an analog audio signal corresponding to the target audio signal; the audio output circuit selection module is used to, when neither the first audio output circuit nor the second audio output circuit is outputting audio, select the first audio output circuit for audio output if the audio codec module outputs a first analog audio signal, and select the second audio output circuit for audio output if the audio codec module outputs a second analog audio signal. If the second analog audio signal is selected, the second audio output circuit is selected for audio output. Furthermore, during the process of outputting the first analog audio signal based on the first audio output circuit, if the audio codec module outputs the second analog audio signal, the first audio output circuit is selected for audio output of the second analog audio signal. Wherein, the first analog audio signal is the analog audio signal corresponding to the first audio signal, and the second analog audio signal is the analog audio signal corresponding to the second audio signal.

Furthermore, when the first audio output circuit outputs a first analog audio signal, if the audio codec module outputs a second analog audio signal with higher priority, the system will not select the second audio output circuit to output the second analog audio signal; instead, it will still select the first audio output circuit to output the second analog audio signal. Since the maximum playback volume corresponding to the first audio output circuit is limited by the circuit design and is far less than the range tolerable by the human ear, the abrupt changes in output volume seen in existing technologies will not occur.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In the process of inventing this invention, the inventors discovered that in the technical solution of combining the speaker and receiver into one, the broadband and narrowband multi-mode terminal is a mission-critical terminal with a call mechanism that interrupts low-priority calls with high priority.

[0049] For example, when existing broadband and narrowband multi-mode terminals make public network calls, POC individual calls, or narrowband full-duplex calls, if other high-priority calls such as narrowband group calls or emergency calls come in, the narrowband group calls or emergency calls will take priority. At this time, the original call will be interrupted and the call will be played through the external speaker. Among them, POC (Push-Talk Over Cellular) is a derivative service of traditional trunked radio systems, i.e., PTT (Push-To-Talk), on mobile public networks. It enables wide-area trunked radio communication services for media information such as voice, text, pictures, and video through mobile public networks (such as 2G / 3G / 4G networks).

[0050] Therefore, if the audio control circuit is poorly designed, the volume will suddenly increase during the conversion process, which will have a very bad impact on customers. This is also a very obvious technical defect in the current technology.

[0051] Based on this, the present invention proposes an audio system that, while solving the problem of making electronic devices larger and thinner, can also improve the final audio output effect of the audio system, greatly enhancing the user experience.

[0052] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] refer to Figure 1 , Figure 1 This is a schematic diagram of the principle structure of an audio system provided in an embodiment of the present invention.

[0054] The audio system includes: a signal transceiver module 11, an audio codec module 12, an audio output circuit selection module 13, a first audio output circuit A, a second audio output circuit B, and an electroacoustic conversion unit 14.

[0055] The transceiver module 11 is used to receive a target audio signal, wherein the target audio signal is a first audio signal or a second audio signal with a higher priority than the first audio signal;

[0056] The audio codec module 12 is used to convert the target audio signal in digital form into analog form to obtain the analog audio signal corresponding to the target audio signal;

[0057] The audio circuit selection module 13 is configured to, when neither the first audio output circuit A nor the second audio output circuit B is outputting audio, select the first audio output circuit A for audio output if the audio codec module 12 outputs a first analog audio signal, and select the second audio output circuit B for audio output if the audio codec module 12 outputs a second analog audio signal; and, during the process of outputting audio to the first analog audio signal based on the first audio output circuit A, if the audio codec module 12 outputs a second analog audio signal, select the first audio output circuit A for audio output to the second analog audio signal; wherein, the first analog audio signal is the analog audio signal corresponding to the first audio signal, and the second analog audio signal is the analog audio signal corresponding to the second audio signal.

[0058] Optionally, when the audio circuit selection module 13 selects the first audio output circuit A to output the second analog audio signal, the audio output volume is increased; preferably, the audio output volume is increased to the maximum playback volume of the current audio output circuit.

[0059] The first audio output circuit A is used to drive the electroacoustic conversion unit to output audio based on the analog audio signal output by the audio codec module 12;

[0060] The second audio output circuit B is used to amplify the analog audio signal output by the audio codec module 12 in order to drive the electroacoustic conversion unit to output audio.

[0061] In this embodiment, the electroacoustic conversion unit 14 includes, but is not limited to, a speaker.

[0062] In this audio system that combines the speaker and receiver into one unit, two independent audio output circuits are connected to a single electroacoustic conversion unit. Different audio output circuits are used to output different audio signals, enabling the electroacoustic conversion unit to achieve different audio effects and thus improve the user experience.

[0063] This can be understood as follows: the first audio output circuit A is in receiver mode; the second audio output circuit B is in speaker mode.

[0064] In speaker mode, the analog audio signal output by the audio codec module 12 includes, but is not limited to, being amplified by a high-power audio amplifier, and the amplified audio signal is used to drive the electroacoustic conversion unit 14 to output audio.

[0065] In receiver mode, the analog audio signal output by the audio codec module 12 is not amplified by a high-power audio amplifier, but directly drives the electroacoustic conversion unit 14 to output audio based on the analog audio signal output by the audio codec module 12.

[0066] This achieves two different modes of audio output. During the audio system's output of the first analog audio signal based on the first audio output circuit A, if the audio codec module 12 outputs the second analog audio signal, even if the second analog audio signal is defaulted to the second audio output circuit B, the audio system provided in this embodiment still drives the electroacoustic conversion unit 14 to output audio based on the second analog audio signal through the first audio output circuit A, and increases the audio output volume. Since the maximum playback volume corresponding to the first audio output circuit A is limited by the circuit design and is far less than the range that the human ear can tolerate, the sudden change in output volume seen in the prior art will not occur.

[0067] In other words, this audio system, which combines the speaker and receiver into one audio system, uses two independent audio output circuits connected to a single electroacoustic conversion unit to achieve different audio effects, thereby improving the user experience.

[0068] Specifically, in order to achieve the switching of different audio output circuits, the embodiments of the present invention include, but are not limited to, using an audio output circuit selection module 13 to select the audio output circuit, which can be simply understood as an audio output circuit selection switch.

[0069] Furthermore, in this embodiment of the invention, the audio codec module 12 is also called an audio codec, and its English name is Audio Codec; where Codec is a codec, which is a hybrid of encoder and decoder.

[0070] An audio codec is a device or computer program that can encode and decode digital audio streams.

[0071] From a software perspective, an audio codec is a computer program that executes algorithms to compress / decompress digital audio data according to a specific audio file format or streaming media format.

[0072] The goal of this algorithm is to represent high-fidelity audio signals using the fewest possible bits while maintaining quality, thereby effectively reducing storage space and the bandwidth required to transmit stored audio files.

[0073] From a hardware perspective, an audio codec is a separate device that can encode analog audio to digital audio and decode digital audio to analog audio.

[0074] In other words, an audio codec contains analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) that operate on the same clock, and are used, for example, in a sound card to support audio input and output.

[0075] Optionally, in another embodiment of the invention, reference is made to... Figure 2 , Figure 2 This is a schematic diagram of the principle structure of another audio system provided in an embodiment of the present invention.

[0076] The signal transceiver module 11 includes at least two transceiver components 111;

[0077] Any of the transceiver components 111 includes: a radio frequency module 112 and a baseband module 113.

[0078] In this embodiment, multiple transceiver components can work in standby mode simultaneously, but at any given time only one transceiver component can receive or initiate a voice call, and when receiving or initiating a voice call, it exclusively uses the entire audio output channel.

[0079] Optionally, in another embodiment of the invention, reference is made to... Figure 3 , Figure 3 This is a schematic diagram of the principle structure of another audio system provided in an embodiment of the present invention.

[0080] The signal transceiver module 11 includes: an LTE transceiver component 114 and a DMR transceiver component 115;

[0081] The LTE transceiver assembly 114 includes: an LTE radio frequency module 116 and a broadband baseband module 117;

[0082] The DMR transceiver assembly 115 includes a DMR radio frequency module 118 and a narrowband baseband module 119.

[0083] In this embodiment, LTE (3GPP Long Term Evolution) is a third-generation wireless communication standard.

[0084] DMR (Digital Mobile Radio) is a digital wireless communication standard developed by the European Telecommunications Standards Institute (ETSI) specifically for professional mobile wireless communication users.

[0085] Optionally, in another embodiment of the invention, reference is made to... Figure 4 , Figure 4 This is a schematic diagram of the principle structure of another audio system provided in an embodiment of the present invention.

[0086] The audio system also includes:

[0087] An audio amplifier 15 is installed on the second audio output circuit B;

[0088] The audio amplifier 15 is used to amplify the analog audio signal output by the audio codec module 12 to drive the electroacoustic conversion unit 14 to output audio. That is, the audio amplifier 15 is used to amplify the second analog audio signal to drive the electroacoustic conversion unit 14 to output audio.

[0089] In this embodiment, the second audio output circuit B can be understood as a speaker mode.

[0090] In speaker mode, the analog audio signal output by the audio codec module 12 includes, but is not limited to, being amplified by a high-power audio amplifier 15, and the amplified analog audio signal is used to drive the electroacoustic conversion unit 14 to output high-power audio.

[0091] It should be noted that its maximum output power is over 2W.

[0092] Optionally, in another embodiment of the invention, reference is made to... Figure 5 , Figure 5 This is a schematic diagram of the principle structure of another audio system provided in an embodiment of the present invention.

[0093] The audio system also includes:

[0094] A protection module 16 is installed on the first audio output circuit A;

[0095] The protection module 16 is used to drive the electroacoustic conversion unit 14 to output audio based on the analog audio signal output by the audio codec module 12.

[0096] The protection module 16 is also used to prevent the amplified analog audio signal from returning to the audio codec module 12.

[0097] In this embodiment, the first audio output circuit A is in receiver mode.

[0098] In receiver mode, the analog audio signal output by the audio codec module 12 is not amplified by a high-power audio amplifier. Instead, the analog audio signal output by the audio codec module 12 is directly driven by the protection module 16 to drive the electroacoustic conversion unit 14 to output audio at normal power.

[0099] Furthermore, the protection module 16 is also used to prevent the analog audio signal amplified by the audio amplifier 15 on the second audio output circuit B from returning to the audio codec module 12, so as to improve the performance of the audio system.

[0100] Optionally, based on the above embodiments of the present invention, another embodiment of the present invention also provides a control method for an audio system, see reference. Figure 6 , Figure 6 This is a flowchart illustrating a control method for an audio system provided in an embodiment of the present invention.

[0101] This control method is based on the audio system described in the above embodiments of the present invention, and the control method includes:

[0102] S101: When the first audio signal is received, the first audio signal in digital form is converted into analog form to obtain the first analog audio signal.

[0103] In this step, the first audio signal is received by the signal transceiver module, and the first audio signal in digital form is converted into the first analog audio signal by the audio codec module.

[0104] Optionally, the first audio signal includes: audio signals corresponding to full-duplex calls and / or public network calls.

[0105] S102: The first audio output circuit drives the electroacoustic conversion unit to output audio based on the first analog audio signal.

[0106] In this step, the first audio signal has a lower priority. In normal operation mode, it is in receiver mode by default, that is, it defaults to the first audio output circuit.

[0107] In receiver mode, the first analog audio signal is not amplified by a high-power audio amplifier, but directly drives the electroacoustic conversion unit to output audio.

[0108] S103: During the process of outputting audio to the first analog audio signal, if a second audio signal with a higher priority than the first audio signal is obtained, the first audio output circuit drives the electroacoustic conversion unit to output audio based on the second analog audio signal.

[0109] Wherein, the second analog audio signal is the analog audio signal corresponding to the second audio signal.

[0110] Optionally, the second audio signal includes: the audio signal corresponding to a group call or emergency call.

[0111] In this embodiment, when the audio system is in public network telephone / POC individual call / narrowband full-duplex call, its audio output circuit is the first audio output circuit, that is, in receiver mode.

[0112] At this time, if a narrowband group call or an emergency call comes in, the original low-priority call will be interrupted, and the current receiver mode will be maintained by default. That is, the first audio output circuit will still drive the electroacoustic conversion unit to output audio based on the second analog audio signal.

[0113] Optionally, when the first audio output circuit drives the electroacoustic conversion unit to output audio based on the second analog audio signal, the audio output volume is increased; preferably, the audio output volume is increased to the maximum playback volume of the current audio output circuit.

[0114] It should be noted that the maximum playback volume corresponding to the first audio output circuit is limited by the circuit design and is much smaller than the range that the human ear can tolerate, but is significantly larger than the volume of the receiver mode in order to achieve the purpose of high-priority call inquiries.

[0115] Optionally, in another embodiment of the invention, reference is made to... Figure 7 , Figure 7 This is a flowchart illustrating another control method for an audio system provided in an embodiment of the present invention.

[0116] This control method is based on the audio system described in the above embodiments of the present invention, and the control method includes:

[0117] S201: When outputting audio based on the first audio output circuit, determine whether there is an external control signal connected.

[0118] The external control signal is used to enable the audio system to output audio based on the second audio output circuit;

[0119] S202: If so, the electroacoustic conversion unit is driven to output audio based on the second audio output circuit, and the audio output volume is controlled.

[0120] In this embodiment, when the audio system is in public network telephone / POC individual call / narrowband full-duplex call, its audio output circuit is the first audio output circuit, that is, in receiver mode.

[0121] When there is a situation where the speaker mode is manually switched, that is, when it is determined that an external control signal is connected, the audio system switches to the second audio output circuit for audio output based on the external control signal. After switching, the audio output volume also needs to be controlled, for example, the audio output volume is controlled to 10% of the current maximum playback volume of the audio output circuit.

[0122] If you need to adjust the volume, you will need to do so through external operation.

[0123] After the call ends, restore the default speaker volume in speaker mode.

[0124] Optionally, in another embodiment of the invention, reference is made to... Figure 8 , Figure 8 This is a flowchart illustrating another control method for an audio system provided in an embodiment of the present invention.

[0125] In this embodiment, the control method further includes:

[0126] S301: When the first audio output circuit and the second audio output circuit are not outputting audio, if the second audio signal is received, the second audio signal in digital form is converted into analog form to obtain a second analog audio signal.

[0127] In this step, the second audio signal is received by the signal transceiver module, and the second audio signal in digital form is converted into the second analog audio signal by the audio codec module.

[0128] S302: The second analog audio signal is amplified by the second audio output circuit to drive the electroacoustic conversion unit to output audio.

[0129] In this step, the second audio signal has a higher priority. In normal operation mode, it is in speaker mode by default, that is, it defaults to using the second audio output circuit.

[0130] In speaker mode, the second analog audio signal includes, but is not limited to, being amplified by a high-power audio amplifier, and the amplified second analog audio signal is used to drive the electroacoustic conversion unit to output audio.
